The PCB has said it will lodge a protest with the International Cricket Council over remarks made by match referee Chris Broad criticising security following Tuesday's attack on the Sri Lanka team bus in Lahore.

"It is very unfortunate what he has said," Pakistan Cricket Board chairman Ejaz Butt said today. "All he has said is totally untrue and fabricated."

Former England player Broad, travelling behind the team in a another bus whose driver was killed, told a news conference he and colleagues were left like "sitting ducks" by policemen during the attack.

Butt said the government had done all it could to provide the best possible security for the visiting team and officials.

"Let me tell you the same security plan was implemented for the test series as when Sri Lanka came to play the one-day series. Broad himself appreciated the plans," he said.

"I think the incident, which is unfortunate, is being exaggerated.

"Right now agencies are carrying out two investigations into the incident and we should wait for their findings before saying the security was inadequate," Butt added.

Former England bowler Dominic Cork was also caught up in the incident.

"If Ejaz Butt believes that security was enough at an international sports event then he's wrong and he should live and die by the words he's come out with," Cork told Sky Sports News.

"Ejaz Butt is completely and utterly out of order."

Six Sri Lankan players and their assistant coach were injured in the incident and seven Pakistanis, including six police, were killed.
